I was a fairly keen marathon runner and used to train most days until 6 years ago at the age of 50 when I gave it up from one day to the next. I then spent a lot of time sitting at the computer.
Since then I get leg pain along the back of the leg twice a year. It concentrates at the back outside (is that a tendon there?) of the knee and behind the ankle. It feels like it is stiffening up. After about 4 days the pain focuses on the front of the knee which swells up and is agony to try to bend. At the same time, the pain spreads across the ankle which often swells up also. The whole attack from start to finish lasts about 3 weeks normally.
From a non medical point of view it feels like the tendons in the lower leg are contracting and pulling both the knee and ankle in a tug of war eventually pulling something out of place.
I have been to specialist knee doctor who took MR tests, X rays and chemical tests and can find nothing wrong. He sent me to a rheumatologist who carried out another batch of chemical tests and x rays of hands and feet to look for signs of arthritis but could find nothing suspect.
Is this possibly just tendinitis? Do tendons / ligaments ever shrink and pull joints out of place?
Thanks in anticipation.
